Coke Oven Core
Starts the Coke oven.
The core sits at floor level in the middle of the wall the two chambers share. Place it first, then ctrl plus shift plus right-click it to raise the build outline of the Coke oven and its shopping list; the chambers, the doors and the crown lids are laid around it. Its side variant fixes which way the bank faces. It is also the block to read while the oven works, because each chamber bakes on its own clock: the core names the chamber that is idle, the chamber that is standing open, and how far each bake has come.
